Thassa's Oracle

When this creature enters, look at the top X
cards of your library, where X is your devotion
to blue. Put up to one of them on top of your
library and the rest on the bottom of your
library in a random order. If X is greater than
or equal to the number of cards in your
library, you win the game. (Each {u} Blue
in the mana costs of permanents you control
counts toward your devotion to blue.)
